Compatibility between EN-EL18 series Batteries and MH-26a & MH-33 Chargers with Z 9NIK-BAT-EN-EL18D
EN-EL18, EN-EL18a, EN-EL18b, EN-EL18c and EN-EL18d Rechargeable Li-ion batteries
All five batteries are cross-compatible, the main difference between them is that the EN-EL18 battery capacity of 2000mAh was increased to 2500mAh in the EN-EL18a, b and c batteries and to 3300mAh in the EN-EL18d battery.
Due to the lower capacity of the EN-EL18 battery, when it is used in a camera designed for use with the EN-EL18a, b, c or d battery, it will result in lower than expected performance (fewer pictures can be taken with a single charge). To guarantee your camera performs as expected, please use the battery specified in the user manual.
The EN-EL18a, b and c battery specifications are the same however, Nikon chose to rename the battery at different points in time.
MH-26, MH-26a and MH-33 battery chargers
The EN-EL18, EN-EL18a, EN-EL18b and EN-EL18c batteries can be used with both the MH-26 and MH-26a battery chargers. The chargers have the same specification except that the MH-26a was modified so that when the BT-A10 adapter is attached to it, it can charge the EN-EL4/EN-EL4a (batteries for the D3/D3S).
The EN-EL18b, EN-EL18c and EN-EL18d batteries can be used with the MH-33 battery charger.
The EN-EL18d battery cannot be used with the MH-26 and MH-26a battery chargers due to its larger capacity.
